The preparation method of graphene oxide with high barrier/Nylon Nanocomposite, comprises the following steps：(1) graphene oxide grafting nylon (GO g PA) is prepared using graphene oxide (GO) and nylon (PA) reaction, i.e., is reacted using GO surface carboxyl groups and epoxy radicals with PA Amino End Groups and PA is grafted to GO surfaces；(2) after PA, GO g PA, antioxidant and UV absorbers being well mixed on homogenizer, in common double screw extruder, it is blended under certain temperature and rotating speed, extruding pelletization, obtain nylon/graphene oxide (PA/GO) nano composite material of high barrier.The inventive method is simple, and the graphene oxide that surface is modified in graphene oxide/Nylon Nanocomposite is evenly distributed, and the barrier of the material is significantly improved, while mechanical strength and heat resistance etc. are also improved to a certain extent. |
